The SPoRT ADAS depicts the location of the cold front that may bring severe weather to the Tennessee Valley later tonight. This top image above shows the 1600 UTC (11:00 Central) SPoRT ADAS dew point temperature surface analysis in degrees Fahrenheit. Ahead of the cold front, dew point temperatures are in the upper 50s across Northern Alabama with values in excess of 64 across the Gulf Coast. Behind the cold front (over Kansas), dew point temperatures are in the teens. The SPoRT ADAS performs well in depicting this moisture gradient and leading edge of the precipitation as seen in the 1618 UTC (11:18 Central) base reflectivity (bottom image above; from the NWS). Here, the leading edge of the strongest precipitation is right along the moisture gradient depicted in the SPoRT ADAS.
